IMPROVEMENT IN FASTENERS FCR THE MEETING-RAILS OF SASHES.

Specification forming part of Letters Patent No. 139,895, dated J une17, 1873 application led May 2, 1873.

To all whom it may concern:

Be it known that I, MoRToN JUDD, of Wallingford, in the county of NewHaven and State of Connecticut, have invented an Improvement in Window-Sash Fastenings, of which the following is a specification:

The object of this invention is to prevent the lever of the fasteningbeing moved by a knife or thin instrument introduced between themeeting-rails of the sash. The swinging lever is made with a notch in011e side to effect said object, and also with a curved end that carriesthe knob and turns aside clear of the sash, and allows the boxcontaining the fulcrum of the lever to be made with a cap that issecured by the fulcrum pivot or screw.

In the drawing, Figure 1 is a plan of the fastening with the cap-platein section, and Fig. 2 is a vertical section at the line w x.

The sash-fastening lever a is made with an eye at one end, through whichthe pivot-screw or rivet b passes to connect such lever to the plates cand d. The plate c is to be attached to the meeting-rail of the uppersash by the screws e, and upon such plate c is a threesided box, f, uponthe upper edges of which the cap-plate d rests, and is secured by thesaid pivot b. The side of the box at 2 does not extend to the front edgeof the plate c for a purpose hereafter named, but the pivot b is withina straight line drawn fromthe edge 2 to the edge 3 of the box f, so thatthe capplate d will be rmly held to the top edges of such box by theyscrew or rivet b. The eye of the lever a has three bearing-points forthe spring h, so that the lever a will be held in the position shown bythe full lines in Fig. 1, or by the dotted lines at 4, or back out ofthe way of the lower sash, as represented by the dotted lines at 5.

The shape of this lever c is peculiar, the end curving around andreceiving the button k; the object of this being to allow the lever tooccupy the space between the edge 2 ofthe box and the edge of the platec, and throw the button 7c sufficiently back to be clear of themeeting-rail of the lower sash. This shape given to the lever a is alsoadvantageous in keeping the button lc forward and over the locking-platel, when the lever a is thrown to the extreme position, shown by fulllines in Fig. 1. I remark that the lockingplate land the downwardprojection from the lever c are of usual character. A

The lever e hasV a projection, 6, forming a notch or angle at one side,and in case an eifort is made to move the lever a by a knife or otherthin instrument introduced between the meeting-rails, the same entersthis notch, and, in consequence of the lever not standing at rightangles to the 'meeting-rails, any movement given to such lever will bindthe knife against the meeting-rail of the lower sash in such a manner asto prevent further motion. Under ordinary circumstances the lever a willonly be moved to the position shown by the dotted lines at 4, but whenmoved to the position shown by full lines, Fig. 1, it will beburglarproof.

I claim as my invention- 1. The sash-fastening lever a, made with theprojection 6 at one side, in combination with the spring h, and bearingat the eye of the lever to hold the same in a position diagonal to themeeting-rails of the sash, for the purposes set forth.

2. The box f cast upon the plate c, in com' bination with the cap-plated and rivet or screw b that secures said cap-plate and forms a pivot forthe lever a, as set forth.

Signed by me this 22d day of April, A. D.
